"At first it was just my voice. Then another voice came creeping in and I thought 'this should be a duet if I can find the right person.' I needed to find someone really indicting. She was totally committed."

Andrew Bird has shared another cut from his forthcoming album Are You Serious, which is set for release on April 1st via Loma Vista. The new tune features Fiona Apple and is called 'Left Handed Kisses': "The song began as an internal dialogue," he explains. "At first it was just my voice. Then another voice came creeping in and I thought 'this should be a duet if I can find the right person.' I needed to find someone really indicting. She was totally committed."

He's also expanded his world tour, which includes a show at London's Roundhouse on May 4th. Check out all his UK/EU dates below.
